You think that's interesting consider the sqrt of 2, fantastic number, its what makes our system of paper sizing work.

Or Pi, how did anyone actually work out the value of that number anyway?
No seriously, you can measure it, but not accurately, someone had to work it out.

But in answer to your question, it's mostly down to using sensible units of measurement, imagine what it would be if you were using imperial units...

This will bend your mind, you think in numbers based around ten. But a better number to base it around would be 12. Only 12 wouldn't be twelve, it would a be 10, but with two extra numbers between it and 9.

unklehomered - Pi is a non recurring irrational number so can never be fully worked out, just calculated to LOTS of decimal places. And BTW there are 10 types of people in the world, those who understand binary and those who don't.

I know C is calculated as a ration between the size of two forces (I am sure it was Maxwell that did this) so it follows that in E=MC2 Eistein used Maxwells work to link these forces to mass and energy.

Again I might be completely wrong, and it was a long time since I did my natural Sciences degree!
